If you have been looking for an instrument for contact angle measurement, you have probably noticed that measuring contact angle is not always enough. Although contact angle measurement does give you an indication on the wetting properties of the surface, it is always a value that depends on the measurement liquid used.Read More
Nanoparticles and thin films made from nanoparticles are gaining recognition and use in various products and applications including displays, sensors and energy storage. These types of products often require well-controlled particle organization, density and film thickness to achieve optimal performance and efficiency.
If you are working with inks, paints or other contaminating liquids and thinking of measuring contact angles, we have good news for you. By having a disposable tip dispenser, you can get away with messy sample handling and perform your measurements even faster.
Most effort in a spectroscopic ellipsometry and QCM-D measurement is done setting up the instruments and liquid flow assembly. To help make life a little easier, consider the following tips & tricks.Read More
Superhydrophobic surfaces are gaining more and more attention as new applications for them arises. For surface to be superhydrophobic, it has to fulfil two requirements. The static contact angle has to be over 150 degrees but in addition to that, the surface has to have a low contact angle hysteresis. For this reason, measurement of dynamic contact angles is especially important when superhydrophobic surfaces are studied.Read More
As the exploration of new oil reservoirs is slowing down, there is a need to be able to utilize the current oil reservoirs more efficiently. After primary and secondary recovery, at least 50% of the original oil is left behind in the reservoir . Additional injections of fluids like polymers, surfactants or different gases are commonly used to displace and dissolve some of the remaining oil. This process is called tertiary or enhanced oil recovery (EOR) and can lead to an additional 8-16 % uptake of original oil in place (OOIP) .
Superhydrophobic surfaces were an instant hit in the scientific community when they were introduced over two decades ago. Since then thousands of publications have documented superhydrophobicity being achieved on various different substrates, from glass to fabrics.
The great potential of superhydrophobic surfaces was apparent early on. Applications ranging from self-cleaning windows to anti-acing surfaces and non-wetting fabrics appear commonly in the literature.

How does a nanomaterial interact with a cell?
How nanomaterials interact with the environment after they have been disposed of has many implications for potential toxicity and health concerns. Whether nanomaterials are being incorporated into commercial goods for their anti-microbial properties such as in work-out clothes or used for targeted drug therapies their overall prevalence is increasing. Therefore, the likelihood of someone coming into contact with these materials is also increasing.Read More

Superhydrophobic surfaces toward real-world applications
Soft Matter and Wetting research group at Aalto University published insights about superhydrophobic surfaces in Science recently1. The non-wetting surfaces have experienced an enormous boost of interest after the observation of superhydrophobicity and self-cleaning effect in natural lotus leaves.Read More
